In recent years, the trend of engineering plastics instead of metal materials is significant. Moreover, the prosperous terminal product market and the rise of biobased materials further fuelling the global PBT market. The market size of global PBT market reached USD 33.7 billion in 2014, and it is estimated this market will still grow with a CAGR of nearly 7.3% from 2014 to 2019.

Asian-Pacific is an important production and consumption market of PBT, where 53.6% of global PBT market share accounted for. Due to the dramatic development of automobile and electronics, China has become the largest PBT consumer in Asian-Pacific.

The demand of PBT in China raised year by year, currently the output still cannot meet the demand. Some specific grade products still rely on import. In 2014 the capacity of PBT in China was about 768 kt, operating rate was about 84%. In 2015, some PBT plant still under construction, the total capacity of PBT in China would exceed 800 kt in 2017. At that time, the self-sufficiency of PBT in China will be further improved, but import products cannot be totally replaced.

Electronics accounts for nearly 60% of total downstream consumption of PBT in China. Currently China has become the fastest growth and largest market of global connector industry. From 2014 to 2019, China
